Chordata
(
chordates
o
chordatos
) es un
phylo
animal characterisate per le presentia de un chorda neural tubular dorsal o
notochorda
, sia durante tote le disveloppamento, sia in alicunes del phases de lor vita. Il ha tres subphylos:
Cephalochordata
,
Tunicata
e
Vertebrata
.
1 = cerebral protuberantia
4 =
coda post-anal
14 = apertura buccal
16 = sensor de lumine
Le chordatos forma un
phylo
? un gruppo de animales con un commun plan del corpore
